BIRNS XT120 Model 5651 Underwater Light

General Information

The BIRNS XT120 is the world's most durable and versatile small general-purpose underwater light. Proven by experience, the XT120 was developed in the early-1980's and, apart from periodic upgrades, remains essentially unchanged from the original, superb style. Many XT120's in the field from the 1980's are still in use!

Applications

The XT120 is versatile, and is used by divers, on cameras, ROV's, etc. It can be mounted on a helmet, hand-held, or yoke-mounted, with choice of 120 or 240 volts, 100 to 250-watt lamp, and eight different lens options. It's an excellent light for general-purpose illumination, and is also very good for color or black and white filming and videotaping.
